Friendly Guide
Features
• Eight RJ-45 ports for 10Base-T network connection
• 1 RJ-45 uplink port for hub-to-hub connection (used to expand network)
• Easy accommodation of daisy-chain Ethernet topologies (up to four hubs can

• Power, collision, and link/activity LEDs that aid in problem diagnosis and
simple network management
• Constant monitoring of ports for signal quality
• Automatic partitioning of ports that are producing noise or excessive
collisions; automatic reconnection once errors are cleared

• Friendly Guide (this card)
• Product registration card
• Eight-port (FH10T8) FriendlyNet Hub
• External power adapter
• Wall-mount kit (two tapping screws,
two screw anchors)
What you’ll need:
•Straight-through twisted-pair network cable less than 100 meters long fo
each station (between the station and hub, including all patch cables and cro
connect wires)
2Before you start
• Find out what AC power-line voltage is used in your area; make sure your hub
AC/DC power adapter matches this voltage
• The DC output power should be 5 V 800mA
• If you want to mount the hub on a wall, see the section “How to wall mount
the FriendlyNet Hub” on the reverse side of this card
Note: It’s OK to connect or disconnect network cable segments while the
FriendlyNet Hub is plugged in and powered on.

c. Multiple network stations and hubs connected together
Note: If you need help determining a configuration for your network, see the
section “Network ideas and concepts” on the reverse side of this card.
1. Connect one end of the network cable to one of the FriendlyNet Hub’s RJ-45
ports (this is any port except the port labeled “Uplink”).
2. Connect the cable’s other end to a network station’s Ethernet adapter.

3a
1. Designate one FriendlyNet Hub as the “primary” hub.
2. Insert one end of the network cable into one of the primary hub’s RJ-45
ports.
3. Insert the other end of the cable into the secondary hub’s Uplink port.
• When the Uplink port on a hub is used, the hub’s RJ-45 port #8 can NOT be
used to connect to a network station, and vice versa.
• It’s OK to interconnect FriendlyNet hubs, however, the path between any two
network stations can’t exceed more than four hubs and five cable segments.
• You may use both 5 and 8 port Ethernet hubs in the same network.
• When hubs are cascaded, all network stations remain on the same network.

Please refer to the previous two sections for installation details. Keep in mind:
• Your Ethernet network configuration must comply with the IEEE 802.3 stan-
dard.
• No more than five cable segments can be connected between any two networ
k
stations.
• No more than four hubs can be used between any two network stations.
5 segments, at most, may be connected by
4repeaters in a single point-to-point path;
3of the segments may have attached nodes;
2segments use inter-repeater links for distance and have no attached nodes
IEEE Ethernet 5-4-3-2 Repeater Rule:
How to wall mount the FriendlyNet Hub
If you like, the FriendlyNet Hub can be secured to a wall or countertop.
1. Screw one of the enclosed 1/2-inch screws into a wall or countertop, leaving
about 1/4 inch of screw threads exposed.
2. Align the other screw with the first screw, leaving approximately 3 inches
between the two.
3. Screw the second screw in.
4. Line up the keyholes on the bottom of the FriendlyNet Hub with the mounted
screws.
5. Hang or place the hub on the screws.
How to interpret the LED indicators
The FriendlyNet Hub’s front panel has several LEDs that tell you what is going on
with the FriendlyNet Hub and your network.
Power (PWR) green; lights when the FriendlyNet Hub is receiving power.
Collision (COL) yellow; lights when two or more workstations are simultaneously
attempting to transmit packets.
Note: This is not an error condition. Collisions normally occur
when traffic flows across Ethernet networks. However, an
excessively high number of collisions may indicate that your
network is overly congested.
Link/Activity green; represent each of the eight 10Base-T ports, light when
a proper link between the station and the hub port exists. They
blink when the ports are receiving network traffic.
Network ideas and concepts
Need help setting up your Ethernet network? Here are a few ways you can
configure it.
Star topology
You can connect up to eight workstations (also known as “nodes”) to one
FriendlyNet 8-Port Hub. This is called a star topology because multiple ”points
”
come off of one hub (also known as a repeater).
One of the biggest advantages of using a star topology is that troubleshooting
easy, as each segment supports only one attachment (a star topology must comp
with the IEEE 802.3 connection rules).
Example 1: Stand-alone network (single star topology)
In a stand-alone network, network resources (workstations, printers, etc.) are
connected together by a single hub. The number of network resources that ca
be connected together depend on the number of ports supported by the hub.
For details on setting up a stand-alone network, please see the section “Connec
ing a network station to a hub.”

Network ideas and concepts (continued)
For details on setting up an expanded network, please see the sections “Connect-
ing two hubs” and “Connecting a series of hubs & network stations.”
In an expanded network, multiple network resources are connected together by
multiple hubs, which are “daisy-chained” together.
The number of network resources that can be connected together in an expanded
network are limited to the IEEE 5-4-3-2 repeater rule (see “Connecting a series
of hubs and network stations”).

Solving problems
If your FriendlyNet hub has an LED that is not illuminating, it may be caused b
one of the following problems.
Possible problem Solution
• No twisted-pair cable is connected Check connection
• The link pulse is disabled at the Check network device and power
other end
• No power is flowing to the hub Check to see that it is plugged in
• The twisted-pair connection is faulty Check cable
• There’s a non-10Base-T device at Check network device
the other end
